What do you mean by "default sharepoint custom list"? Can we ever use a SharePoint event handler for a control? Are you sure about what you have written? :laugh: There is no foolish question, there is no final answer...

Thanks a lot for your help. Regards Roozbeh.

Hi, Not to sure why you are getting a problem. Here is an example of how to use it in VC++ (see if it differs to yours) First, the #import #import "D:\My Projects\C++\MyObj\MyObj.tlb" using namespace MyObjLib; Add the namespace to avoid any conflicts with other COM objects you may use that will have the same name. Now when using it: MyObjLib::IMyObjPtr pMyObj = NULL; try { if (SUCCEEDED(pMyObj.CreateInstance(\_\_uuidof(MyObjLib::MyObj))) && pMyObj != NULL) { pMyObj->MyString = \_T("Hello"); } } catch(\_com\_error &e) { } This ultimately will use the wrapper method PutMyString( _bstr_t pVal ) that is defined in the two new files generated by the #import statement. These should be in your Debug/Release directories and called MyObj.tlh and MyObj.tli. Ones the header file, the other the implementation file. Have a look through them to see how your COM object has been wrapped. Hope this has helped, Andy

Go Here[^] Woke up this morning...and got myself a blog

First create the IBaseClass with pure virtual functions of your methods that you want to be derived. Create another class CBaseClass and inherite it from IBaseClass and implement the methods and functions. Now create a new simple ATL object, and in the list of inheritances, also include this CBaseClass. Now you need to add and implement the interface methods that is exposed to the world. If you are thinking of inheriting one COM object from another, then its not possible. Hope i got your question right. MSN Messenger. prakashnadar@msn.com Tip of the day of visual C++ IDE.

How is the CAttachments object producing the interface IAttachment to return? Presumably you must be making a CAttachment object somewhere, or do you have them already created and you're just holding a list of the IAttachment interfaces? Steve S

Yes there was a memory leak in this case and other places. I just placed it in my sig to show that how stupid anyone can get to write that kinda of code. But then i removed it coz i thought it was not rite to make a joke of others programming pratice. MSN Messenger. prakashnadar@msn.com
